簡(jiǎn)單設(shè)置placeHolder字體的大小大小 顏色
NSString*placeholderString =@"搜一搜";
NSMutableAttributedString*placeholder = [[NSMutableAttributedStringalloc]initWithString:placeholderString];
[placeholderaddAttribute:NSFontAttributeNamevalue:[UIFontsystemFontOfSize:14]range:NSMakeRange(0, placeholderString.length)];
[placeholderaddAttribute:NSForegroundColorAttributeNamevalue:[UIColoryellowColor]range:NSMakeRange(0,placeholderString.length)];
self.searchTextField.attributedPlaceholder= placeholder;
要對(duì)UItextField 的光標(biāo) leftView 以及顯示文本 位置 要重寫
